5182 Aluminum Sheet
5182 aluminum sheet is a typical Al-Mg (aluminum-magnesium) rust-proof aluminum alloy belonging to the 5000 series. With good formability, excellent weldability, medium to high strength, and outstanding corrosion resistance — especially superior to 5052 in strength — 5182 is widely regarded as one of the best choices for marine and automotive applications.
MESSAGE
Overview
5182 aluminum sheet is a classic Al-Mg anti-rust alloy belonging to the 5000 series aluminum family. It features medium-to-high mechanical strength, outstanding formability and reliable weldability. Compared with 5052 aluminum alloy, it delivers higher strength and superior salt spray corrosion resistance, making it highly adaptable to humid and severe marine environments. With balanced comprehensive performance, 5182 aluminum sheet is widely applied in packaging, automotive, shipbuilding, and pressure vessel industries.
Specification
Alloy:5182
Temper: O, H111, H116, H32, H34, H321

Feature
Excellent Corrosion Resistance: The high magnesium content gives 5182 aluminum sheet outstanding resistance to salt spray corrosion, making it especially suitable for marine environments and humid conditions.
Good Weldability: Suitable for gas welding (oxy-acetylene), TIG welding, spot welding, and roll welding. It delivers excellent welding performance with minimal post-weld cracking, making it ideal for welded structural components.
High-Quality Surface Treatment: The sheet has high surface smoothness, making it well-suited for anodizing, painting, and other surface processing techniques. This is particularly valuable in automotive and architectural applications.
Good Formability: 5182 offers excellent ductility and deep-drawing capability, suitable for complex stamping and forming operations.
Medium to High Strength: Among the 5000 series, 5182 provides high strength while maintaining good workability, striking an excellent balance between strength and formability.
Application
5182 aluminum sheet is widely applied in the packaging industry for beverage cans, pull tabs, can ends, and can bottoms. In the automotive sector, it is used for body panels such as doors, hoods, and fenders. Beyond that, thanks to its excellent corrosion resistance, weldability, and plasticity, 5182 aluminum sheet is an ideal material for medium- to low-strength non-load-bearing structural parts in liquid or gas environments, such as fuel tanks, lubricant conduits, and liquid containers.
